' Application filed April 5, 1915. Serial No. 19,267.

To all whom it may concern Be it known that I, HIRAM A. HoLznn, acitizen of. the United States, residing at Pittsburg, Kansas, haveinvented acertain new and useful Improvement in Mine-Car Wheelscoflwhichthe following is a full, clear, andexact description, such as Wlllenable others skilled in the art to which it appertains to make and usethe same.

. This invention relates to mine car wheels of the type in which the,axle box isprovided .Wliill a removable member for preve ting thelwheelfrom-moving long1tud1- iislly ot the axle.

Oneohje'ct of my present invention is to provide a wheel structure ofthe character inentione d, in which the axle boxis equipped with aremovable hood of novel design that has vertically-disposed integralbearing ribs which cotiperate with a flange on the hub of the wheel toprevent the wheel from moving longitudinally of the axle, said bearingribs being disposed substantially radially with reference to t e hub ofthe wheel and preferably arranged at the-upper side of the hub onoppositqsidesof the longitudinal axis of the wheel axle.

Another objectis to provide a strong and serviceable Wheel structure formine cars that can be manufactured cheaply and which is so designed thatthe wheel can be applied and removed easily.

thernobjects and desirable features of my invention will be hereinafterpointed out. j F igure 1 of the drawings .is an end elevational View ofa wheel structure embodying my invention.- Fig. 2 is a side'elevationalview of same partly in vertical section, taken on the line 2-2 oflfig. 1. Fig. 3 is a detail view taken on the line 33 of Fig. l; andFig. 4 is a perspective view of the removable hood on the axle box.

Referring to the drawings, which illustrate the preferred form of myinvention, A designates a wheel that is particularly adapted for use onmine cars, trucks and similar vehicles, and l) designates the axle onwhich said wheel is mounted, said wheel having a hub portion 1 thatreceives the outer end portion of the axle B. The axle B is mounted inan axle hox C which is secured to the body of the vehicle (indicated bybroken lines in Fig. 9-), and said axle box isprovided with a removablehood D that provided with connected, If desired, the reinforced andstrengthened prevents the wheel from moving longitudinally of'the axle.In the embodiment of my invention herein shown the hub portion of thehub of the wheel bears against the outer end of the axle box C and saidbox is a vertically-disposed flange or plate portion 4 that projectsupwardly from the portion of the box 0 through which the axlepasses andbears against the side of the vehicle body to which the axle box isconnected, as shown clearly in Fi 2-. This flange or plate portion iswider t an the portion of the box C through which the axle passes and atthe outer ends of same are two forwardly-projecting integral lugs 5 thatare spaced away from each other, .as shown in Fig. 1, said lugs 5 beingtied together by means ofahorizontally-disposed flange at the upper endof the plate portion 4 to which the lugs 5 are integrally lugs 5 can beby means of gussets 4" located at the side edges of the plate portion;and integrally connected to same and to the'lugs The hood D fits betweenthe forwardly-projecting lugs 5 0n the axle box and is retained inposition by means of a removable fastening device 6 that passestransversely through said lugs and hood, said fastening device eitherconsisting of a bolt provided with a nut or a pin provided at one endwith a hole for receiving a cotter key 6,

The hood D has :1 depending portion 7 whose lower edge conforms to thecurvature of the hub portion 1 of the wheel A, and

said depending portion isequipped with two vertically-disposed bearingribs 7" that cooperate with an annular flange 1 on the hub portion ofthe wheel to prevent the whcclffrom moving longitudinally of the axle,said bearing ribs being formed intogral with the hood and arranged atthe side edges of same so that they will be located above the hub of thewheel and on opposite sides of the lon itudinal axis of the. iixlc l3. 4When the hood D is arranged in operative position, as shown in Figs. 1and 2, a horizontally-disposed bearir ig rib 7 at the as shown in Fig.1.

upper end of the hood bears against the flange 4 at the'upper end of theplate portion t of the axle box, and thus transmits the 4 strainswhich'the wheel exerts on the hooddirectly to. the'pla-te portion 4 ofthe axle box C. In other words, the hood D is so designed and arrangedthat any outward movement of the wheel te'ndsto cause the ,hood D toturn on the pin or bolt 6 that holds said hood in position and thusforces the horiz ontally disposed bearing rib 7 at theupper endof thehood tightly against the flange 4 at the upper end of the plate portion4 of the axle box. The lugs 5 that sustain the fastening device 6, ofcourse, take up some of the strains which the wheel exerts on the-hoodD, but, in view of the fact that the flange 1 on the wheel hub exertspressure on the hood at a point below the lugs 5 and thus tends to turnit on its fulcrum, the strains on the lugs 5 are minimized or greatlyreduced. The'bearing ribs 7 on the hood D are arranged substantiallyradially, with reference to the flange 1 on'the hub of the wheel, and asthey have a comparatively slight bearing on said flange, frictionbetween the wheel hub and the member that retains the wheel in positionis reduced to a minimum. Still anotheradvantage of such a structure isthat the bearings' ribs 7 on the hood D engage the wheel hub at only twopoints and on opposite sides of the'longitudinal axis of the wheel axle.

A wheel structure of the character above described can be manufacturedat a low cost,

and it is exceptionallystrong and serviceable, owing to the fact thatthe axle box and I a the removable member on the axle box that retainsthe wheel in position consist of castings of simple design that can bemade large enough and strongl enough to stand up under T e hood Dengages the rough usage.

flange on the hub of the wheel at onl two points and in a: directionsubstantial y raso 3 feature of such a structure is, that the strainsdial with respect to the axis of rotation of the wheel, so that frictionis reduced to a minimum; The wheel can-be applied and removed easily andwithout the necessity of disconnecting the axle box from the body of thevehicle, and still another deslrable on the lugs 5 on the axle box whichreceive the fastening device 6 are reducedto a minimum, on account-ofthe novel deslgn of the retaining hood I) and the way that it 1s mountedon the axle box.

Having thus described my invention, what I claim, and desire to secureby Letters Fat cut is: v v
